public void SetClip(
	Rectangle rect,
	CombineMode combineMode
)

Member of the CombineMode enumeration that specifies the combining operation to use.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a small rectangle for the clipping region.

  • Sets the clipping region to the rectangle with the Replace member.

  • Fills a large rectangle with a solid black brush.

The result is a small, filled, black rectangle.

private void SetClipRectangleCombine(PaintEventArgs e)
{

    // Create rectangle for clipping region.
    Rectangle clipRect = new Rectangle(0, 0, 100, 100);

    // Set clipping region of graphics to rectangle.
    e.Graphics.SetClip(clipRect, CombineMode.Replace);

    // Fill rectangle to demonstrate clip region.
    e.Graphics.FillRectangle(new SolidBrush(Color.Black), 0, 0, 500, 300);
}
